12 Encoder Input Circuit (ENC)
There are a total of eight operating modes.
<P3EN>: 2/3-Phase Input Select
pins used.
<CMP>: Compare Flag
EN0INT register.
<REVERR>: Revolution Error
reading it.
<U/D>: Rotation Direction
<P3EN> selects the number of phase input pins used.
<CMP> is set to 1 when the counter value has been compared to the value programmed in the
The quadrature signals A and B identify the motor rotation direction. <U/D> is set to 1 when the CW
direction is indicated (signal A of the incremental encoder signal is ahead of signal B). <U/D> is cleared
to 0 when the CCW direction is indicated (signal A is behind signal B). <U/D> remains cleared while
<ENRUN> = 0.
Operating modes are defined by <MODE1:0>, <P3EN> and <ZEN> as shown in the following table.
0: 2-phase
1: 3-phase
If <P3EN> is cleared to 0, the ENC decodes two phase inputs.
If <P3EN> is set to 1, the ENC decodes three phase inputs.
In Timer mode, this bit has no effect.
Note: <P3EN> must always be cleared in Encoder mode, irrespective of the number of phase input
0: －
1: Counter compared
<CMP> is cleared to 0 on a read. <CMP> remains cleared when <ENRUN> = 0. Writing to <CMP> has
no effect.
0: －
1: Error occurred.
In Sensor Timer Count mode, <REVERR> is set to 1 when a change in the rotation direction has been
detected. <REVERR> is cleared to 0 on a read. <REVERR> remains cleared when <ENRUN> = 0.
Writing to <REVERR> has no effect.
This bit has an effect only in Sensor Timer Count mode.
Note: Once software has changed the operating mode of the ENC, <REVERR> must be cleared by
0: Counterclockwise (CCW)
1: Clockwise (CW)
